PROBLEM: You are trying to set up an app and it keeps telling you that your website is "Not a Valid URL Format."
SOLUTIONS: This took me about 30 minutes to figure out.
- Make sure that you have http:// at the beginning of the URL.
- Make sure that there isn't a space at the end of the URL.
- Make sure that your URL matches the URL a plugin might be telling you to use.
WHY: It has to be exact for an app to work. However, it would be awfully nice if Twitter could TELL YOU what is WRONG with the URL.
